Two balls are simultaneously dropped from a height of 5.0 m. How long (Tg) does it take for the balls to reach the ground? Use 10 m/s2 for the magnitude of the acceleration due to gravity. Hint: The balls are released from rest at a height of 5.0 m at time t=0s.

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

When does your body conduct current more readily?
